A comparative study of particulated exhaust emissions from two different age of vehicles

Abstract

A study was conducted to quantify the amount of particulate emissions from a new and a year old vehicles of the same engine capacity.
On average, the particulate emissions during idling condition for both the new and the old vehicles were 4.35 mg/m3 and 8.45 mg/m3 respectively. While at 1500 rpm both the new and the old vehicles registered higher particulate emission of 9.33 mg/m3 and 15.79 mg/m3 respectively.
Studies showed that both the age and the engine mode have direct influence on the exhaust emissions.
